HbA1c, or Hemoglobin A1c, is a blood test that measures your average blood sugar (glucose) levels over the past 2 to 3 months. It is commonly used to diagnose and monitor diabetes and prediabetes. Here’s how it works:
- What it measures: HbA1c reflects the percentage of hemoglobin (a protein in red blood cells) that has glucose attached to it. The higher your blood sugar levels, the more glucose attaches to hemoglobin.
- Why it’s important: Unlike daily blood sugar tests, which provide a snapshot of your glucose levels at a single moment, HbA1c gives a broader picture of long-term glucose control.
- Normal ranges:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
This test is crucial for managing diabetes and reducing the risk of complications like heart disease, kidney damage, and nerve problems.
